FIELD OF THE EMBODIMENTS

The present disclosure relates generally to a handsfree elevator control system. More particularly, the present disclosure relates to a handsfree elevator control system that uses beams of light to allow the user to interface with the elevator control system without physically touching said elevator control system.

BACKGROUND

Traditional elevator call button selection is performed when a user selects their desired floor by physically pressing an elevator call button. The elevator system knows which floor to send the elevator because there is electronic coupling of the physical elevator call buttons to the elevator control system. The elevator control system will then transport the elevator cab to the desired floor.

The requirement of physical button selection introduces an issue: an increased likelihood of viral and bacterial transmission spread between users of the elevator. Although, the traditional physical elevator call button interface has always been a source of viral and bacterial transmission, this issue has been brought to the forefront of the public mind due to the COVID-19 Pandemic. Research published in the New England Journal of Medicine shows that the SARS-CoV-2 virus, the virus responsible for COVID-19, can remain active on stainless steel and plastic (materials frequently used on elevator call buttons) surfaces for two to three days.

Surface transmission is especially concerning when coupled with the fact that a 2015 study by Yen Lee Angela Kwok, Jan Gralton, and Mary-Louise McLaws, found medical students (a class of individuals far more informed about the science of viral transmission) to touch their face an average of 23 times per hour. Put simply, the physical button selection in a traditional elevator cab puts all current riders and future riders at an increased risk of viral and/or bacterial transmission.

A solution to the issue of multiple elevator riders touching the physical elevator call buttons would be to have a dedicated elevator operator, where the riders would vocally relay their request to the operator. However, by stationing an elevator operator within the elevator cab there is in an increased risk of droplet or aerosol viral transmission to the operator and subsequently to future riders, preventing any reduction in the transfer of any virus and/or bacteria.

Another solution to the issue of viral and/or bacterial transmission via a physical elevator call button is to increase the frequency in which the buttons are sanitized. However, unless the control panel is sanitized after each contact with the buttons, there is still a likelihood of transmission. Furthermore, both the expense of sanitizing chemicals and labor can be cost prohibitive, in addition to the physical damage that the repeated use of oxidizing agents can have on the elevator and its respective control system. This is especially problematic in times, such as the COVID-19 pandemic, where cleaning supplies are in short supply.

While these units may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present disclosure as disclosed hereafter.

In the present disclosure, where a document, act, or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act, item of knowledge, or any combination thereof that was known at the priority date, publicly available, known to the public, part of common general knowledge or otherwise constitutes prior art under the applicable statutory provisions; or is known to be relevant to an attempt to solve any problem with which the present disclosure is concerned.

While certain aspects of conventional technologies have been discussed to facilitate the present disclosure, no technical aspects are disclaimed. It is contemplated that the claims may encompass one or more of the conventional technical aspects discussed herein.

Note that when a user places their fingers at one of the variable indexing points, the system will register which variable indexing point was selected and will transmit a corresponding signal to the existing elevator control system to simulate said button being selected. In a preferred embodiment, the system will notify a user that their selection was successful. This can be achieved through a speaker playing a voice confirmation or other noise, the corresponding call button being lit up, or some combination thereof. In an embodiment, each of the plurality of call buttons is illuminated when activated. In an embodiment, the sensor control system is directly connected to the elevator call button system.

The present disclosure also provides for a touchless elevator interface device, located adjacent to and for use with an elevator call button system, the elevator call button system having a plurality of call buttons, the device comprising, an elevator call button display comprising a plurality of selection points, where each of the plurality of selection points corresponds to one of the plurality of call buttons. The touchless elevator interface device, located adjacent to the elevator call button system, also comprises a sensor module comprising a plurality of sensors, each sensor comprising, an emitter configured to outwardly emit an infrared beam, a receiver, an application-specific integrated circuit chip, where the application-specific integrated circuit chip is configured to receive an input from the receiver to create a variable indexing point, and where the variable indexing point is determined by an interruption in the infrared beam.

Like the touchless elevator interface device that mounts over the preexisting elevator call buttons, the touchless elevator interface device located adjacent to the elevator call button system, in preferred embodiments, emits an audible confirmation of a user's selection, in the form of a vocal confirmation or other noises. Preferably, the touchless elevator interface device located adjacent to the elevator call button system also comprises at least one status light configured to be in communication with the sensor control system and the elevator call button system. The at least one status light provides confirmation to the user based on their selection.

The present disclosure also provides for a method for selecting a call button of an elevator call button system without touching the call button, through use of touchless elevator interface device having a sensor module comprising a plurality of sensors, each sensor having an emitter configured to outwardly emit an infrared beam, a receiver, an application-specific integrated circuit chip, where the application-specific integrated circuit chip is configured to receive an input from the receiver to create a variable indexing point.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.

Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.

Exhibited below are several solutions for solving the problem of selecting elevator call buttons without physical interaction with the elevator call buttons.

Referring to FIG. 1 , an embodiment of the frame of the touchless elevator call button system. Here, the frame is designed to attach to the base and surround the existing elevator call button panel.

Referring to FIG. 1 , an embodiment of the touchless elevator interface device 300. Here, the system includes a sensor module 302, a sensor control system 306, and a sensor housing 316. In preferred embodiments, the sensor module 302 comprises a plurality of sensors 304, each sensor 304 comprising, an emitter, a receiver, and an application-specific integrated circuit chip. Ideally, the application-specific integrated chip is configured to receive an input from the receiver to create a variable indexing point, where the variable indexing point is determined by an interruption in the infrared beam. Preferably, the sensor control system has a power supply and a control board, the control board having a memory and a processor. In some embodiments the control board is a Raspberry Pi or a similar microcomputer.

Referring to FIG. 1 , preferably, the sensor housing 316 is a rectangular member mounted on the left side of a preexisting elevator call button system, such that the sensor 304 emits infrared beams across the plane of the elevator call buttons 318. In alternate embodiments the sensor housing 316 is located above, below, or to the right of the elevator call buttons 318. Preferably, either the sensor module 302 or the sensor housing 316 is angled slightly away from the elevator call buttons 318, such that the user's finger interrupts the infrared beam 1.5 to 2 inches above the elevator call buttons 318. Alternatively, neither the sensor module 302 nor the sensor housing 316 is angled away from the elevator call buttons 318.

Referring to FIG. 1 , preferably, the sensor housing 316 is mounted to the elevator panel using screws. In this embodiment, screw inserts are placed into the elevator panel and the sensor housing 316 is fastened to the panel with screw. In alternate embodiments, the sensor housing 316 is fastened to the elevator panel with adhesive. In embodiments where the touchless elevator interface device 300 is being used in conjunction with elevator call buttons in an elevator bank, the sensor housing 316 is mounted adjacent to the elevator bank call buttons. In this embodiment, the sensor housing 316 is preferably screwed to the elevator bank wall. Alternatively, the sensor housing 316 may be attached to the elevator bank wall with adhesive.

Referring to FIG. 1 , preferably the sensor housing 316 is made from metal, including: brass, aluminum, stainless steel, or other metals. In alternate embodiments the sensor housing 316 is made from plastic or wood.

Referring to FIG. 1 , a preferable embodiment of the touchless elevator call button system 300 comprises a speaker located proximately to the elevator call button system. In some embodiments the speaker is a passive speaker, thus not requiring a power supply. In other embodiments the speaker is an active speaker, thus requiring a power supply. In that embodiment, the speaker draws from the power supply 308 of the touchless call button system 300 or an independent power supply. In a preferable embodiment, the speaker provides audible confirmation of a floor selection by emitting a noise. In further embodiments, the touchless elevator call button system 300 confirms a user's selection by emitting a vocal rendering of the button that was selected. In alternate embodiments, the speaker provides a secondary noise in conjunction with a vocal rendering. The secondary noise may be a “click,” a chime, a tone, or other similar noises.

Referring to FIG. 1 , a preferred embodiment of the touchless elevator call button system 300 comprises at least one status light located proximately to the elevator call button system. In this preferable embodiment, the status light emits light when a user selects an elevator call button 316. Preferably, the status light is an LED, but can also be an incandescent, fluorescent, or halogen light. In one embodiment the status light remains dark and only illuminates when a selection is made. In another embodiment, the status light is constantly lit, but emits a different color when a selection is made. Preferably, the touchless elevator call button system 300 is lit by additional lights which provide adequate light to a user attempting to make a selection. In further embodiments, the touchless elevator call button system 300 is fitted with an ultraviolet light sanitizer. In other embodiments, the elevator call buttons 316 are fitted with lights such that the elevator call buttons 316 themselves are independently lit. In such an embodiment, the light integrated into the elevator call button 316 acts as a status indicator light, changing colors or illuminating when a selection is made.

Referring to FIG. 2 , an embodiment of the touchless elevator call button system 400. Here, the system includes an elevator call button display 302, a plurality of selection points 304, a sensor module, a sensor control system, and a sensor housing 316. In this embodiment, the touchless elevator call button system 300 is located adjacent to the preexisting elevator call button system. In preferable embodiments the elevator call button display has a plurality of selection points, where each of the plurality of selection points corresponds to one of the plurality of call buttons 318 (See FIG. 1 ). For example, a “ground floor” selection point on the elevator call button display will correspond to the “ground floor” call button on the preexisting elevator call button system.

However, it is not required that the label on the selection point and the label on the corresponding preexisting call button 318 be identical. Instead, in some embodiments, it is preferable to label the selection point differently than the label of the preexisting elevator call button 318. For example, to reduce the footprint of the elevator call button display, it may be advantageous to correlate a selection point labeled “1” to the elevator call button labeled “first floor.” In some embodiments, the selection point may correlate to more than one of the preexisting call buttons. For example, in some embodiments, there is one selection point labeled “emergency,” that correlates to both the elevator call buttons labeled “emergency alarm” and “emergency stop.”

As shown in FIG. 2 , preferably, the selection point is labeled by etching a description of the selection point into the elevator call button display. Alternatively, the selection point is labeled using a sticker, ink, paint, a series of LEDs, laser etching, a placard, or other means of labeling. In further embodiments, the selection points may be labeled with symbols or graphical representations, in addition to or in conjunction with text labels. For example, a selection point that correlates to an “emergency alarm” preexisting elevator call button could be labeled with a graphical representation of a bell.

Preferably, the elevator call button display is mounted on the same wall or the wall directly adjacent to the preexisting elevator call button system. However, in some embodiments, the elevator call button display is mounted to the elevator wall opposite the preexisting elevator call button system.

Here, the system includes an elevator call button display, a plurality of selection points, a sensor module, a sensor control system, and a sensor housing. In this embodiment, the touchless elevator call button system is located on the wall of the elevator bank adjacent to the preexisting elevator call button system. In other embodiments, the touchless elevator call button system is located in the elevator bank, but the system is housed in a kiosk. Preferably, the sensor module comprises a plurality of sensors 408, each sensor comprising an emitter, a receiver, an application-specific integrated circuit chip. In preferable embodiments, the application-specific integrated circuit chip is configured to receive an input from the receiver to create a variable indexing point. The variable indexing point serves as a means of interpreting and mapping the user's desired selection. In most embodiments, the variable indexing point is determined by an interruption in the infrared beam.

Preferably, the sensor control system has a power supply and a control board, the control board having a memory and a processor. In preferable embodiments, the control board is a Raspberry Pi, a single-board computer, or other microcomputer. However, in some embodiments, the sensor control system is directly connected to the preexisting elevator call button system, thus not requiring an independent control board. Similarly, although it is preferable to have an independent power supply for the control board, in some embodiments the control board receives power directly from the preexisting elevator call button system.

In a preferred embodiment, the touchless elevator call button system comprises a speaker located proximately to the elevator call button system. In some embodiments the speaker is a passive speaker, thus not requiring a power supply. In other embodiments the speaker is an active speaker, thus requiring a power supply. In that embodiment, the speaker draws from the power supply of the touchless call button system or an independent power supply. In a preferable embodiment, the speaker provides audible confirmation of a floor selection by emitting a noise. In further embodiments, the touchless elevator call button system confirms a user's selection by emitting a vocal rendering of the button that was selected. In alternate embodiments, the speaker provides a secondary noise in conjunction with a vocal rendering. The secondary noise may be a “click,” a chime, a tone, or other similar noises.

In some embodiments, the system in accordance with the present disclosure comprises at least one status light located proximately to the elevator call button display. In this preferable embodiment, the status light emits light when a user selects a selection point. Preferably, the status light is an LED, but can also be an incandescent, fluorescent, or halogen light. In one embodiment the status light remains dark and only illuminates when a selection is made. In another embodiment, the status light is constantly lit, but emits a different color when a selection is made. Preferably, the elevator call button display is lit by additional lights which provide adequate light to a user attempting to make a selection. In further embodiments, the elevator call button display is fitted with an ultraviolet light sanitizer.

In an alternate embodiment the touchless elevator interface device comprises more than one sensor module. In one embodiment, a first sensor module is affixed along the y-axis and a second sensor module is affixed along the x-axis. In this embodiment, both sensor modules are positioned such that the infrared beams are in the direction of the elevator call buttons.

In further embodiments multiple sensor modules are affixed to multiple elevator call button panels. For example, in situations where sets of elevator call buttons are distant from each other, it is advantageous to utilize multiple sensor modules. In such an embodiment, each sensor module will be coupled with a sensor control system. In alternative embodiments, each sensor module will be coupled to one sensor control system.

Preferably, the memory contains a plurality of computer-readable instructions containing the plurality of call buttons, a mapping scheme correlating each of the plurality of call buttons to one or more of the sensors, and an indexing point reference table having a means for correlating a given variable index point with the mapping scheme. Preferably, the memory contains the mapping scheme in the form of a table, spreadsheet, string, or other data structure where a particular variable indexing point corresponds to a particular variable elevator call button. In embodiments where the touchless elevator interface device is located adjacent to the elevator call button system and comprises an elevator call button display, there is a mapping scheme that correlates a selection point to an elevator call button. This embodiment also utilizes a mapping scheme in the form of a table, spreadsheet, string, or other data structure where a selection point corresponds to an elevator call button.

In preferable embodiments, the elevator call buttons are operational in conjunction with the touchless elevator interface device. In other words, although it is advisable for a user to use the touchless elevator interface device as a primary means of operating the elevator, the physical elevator call buttons will continue to be operational. In alternate embodiments, the physical elevator call buttons are disabled so that only the touchless elevator interface device is operational.

Preferably, the sensor control system is in electronic communication with the sensor module via a wired connection. However, there are other embodiments where the sensor control system is in wireless electronic communication with the sensor module. Also, preferably, the sensor control system is in electronic communication with the elevator call button system via a wired connection. However, there are other embodiments where the sensor control system is in wireless electronic communication with the elevator call button system.
